aualj'zed by the Bacteriology Deparhuent. The quality of the milk thus 

 far produced, has heeu exceptionally good, and the whole project has 

 been very gratifying. 



The department made an exhibit at the State Fair, Detroit, and also 

 in conjunction with the Allied Dairy Association at Saginaw during the 

 year. These exhibits were planned to show the type of work being done 

 at the College and the^y also embodied the lessons of efficient and eco- 

 nomical production. 



EXTENSION SERVICE. 



A great deal of time has been spent by the members of this department 

 in administering and conducting the dairy extension work during the 

 past year. Mr. J. A. Waldron has continued in charge of extension work 

 and Mr. A. C. Baltzer has been assisting in this work throughout the 

 year. Mr. H. E. Dennison was added to the Extension staff on January 

 1st. In addition to these men other members of the department have 

 spent a liberal amount of time doing tield work. New methods have been 

 worked out in the conduct of extension work during the past year. County 

 campaigns have been arranged and carried out in eight counties. This 

 method of getting the iuformation to the farmer has been foun'd the 

 m'os't effective of any A'et devised. The plan in brief is to spend a suf- 

 ficient length of time in a count}', ranging from six to fourteen days, 

 to cover the entire county. One day is spent around each commun- 

 ity center and four to eiglit meetings are held in the bams suiTound- 

 ing the market or community center. A night round-up meeting is held 

 in the town hall or church or elsewhere. Moving pictures are shown and 

 general discussions conducted regarding the subject. There has 

 been a great demand for this sort of w^ork and it will, no doubt, be con- 

 tinued during the coming year. 



Members of the department have also attended farmers' institutes and 

 meetings, and we have furnished judges foT the livestock at many county 

 and district fairs. 



One value feature of the extension work during the past 3'ear is shown 

 by the increase in the number of cow testing associations from eleven 

 to twenty, of which sixteen are in active operation. 



ADVANCED REGISTRY,
